Title: Tunnel boring machine
Inventor: HAGA YOSHIYUKI
IPC: E21D9/04
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To improve workability by filling a ditch excavated in a fixed quantity by a chain cutter for excavating an undermining with a curable material by independently driving a curable-material filling pipe. SOLUTION: An undermining is excavated up to the leg section of an arched guide frame 6 by a chain cutter 2 for excavating the undermining, and the cutter 2 is rotated independently in the direction of the arrow 28 and the excavation of the undermining is promoted and the cutter 2 is extracted at the time of the execution of works. A curable-material filling pipe 4 is turned independently in the direction of the arrow 27, the inside of the undermining is filled with a curable material, and the filling pipe 4 is drawn out. Accordingly, the excavation of the undermining and the injection of the curable material can be conducted continuously even near a leg section at the time of the formation of an arched timbering plate while efficiency can be improved because the curable-material filling pipe is revolved separately, and the curing of the curable material and the closing of the pipe in the curable-material filling pipe can be prevented when the chain cutter is stopped and the speed of excavation is reduced owing to a firm ground.

Title: Joining method for shaft member and fitting member
Inventor: UEDA KATSUHIKO
IPC: B22F5/00
Filed: 1981-07-20
Abstract: PURPOSE:To obviate the formation of diametral cambers on the outside circumferential surface of a fitting member, in the stage of compacting a powdery material for sintering to the fitting member, by providing recesses of a prescribed shape on both side surfaces in the axial direction of the fitting member, and inserting a shaft member into the hole of the fitting member then sintering both. CONSTITUTION:Recesses 8 of a shape hollowed by a depth d from the position nearer the center by a distance (t) from the outside circumferential surface are formed on both side surfaces 6 of a journal piece 4 which is a fitting member to be obtained when liquefied sintering powder is compacted by pressuring or preparatory sintering. A tubular cam shaft 1 is inserted and fitted into the hole 7 of the piece 4, and both are put in a sintering furnace and are subjected to regular sintering, whereby the joining by diffusion and shrinkage is effected. Since the surfaces 6 have the recesses 8, the rate of shrinkage is higher than in the central part in the axial direction of the piece 4 and since the tendency toward cambering of the outside circumferential surface of the piece 4 is negatated each other, an outside circumferential surface 5 parallel exactly with the axial direction can be obtained.

Title: Battery
Inventor: MACHIDA TOYOJI
IPC: H01M50/494
Filed: 1987-05-11
Abstract: PURPOSE:To improve safety by using an insulating porous film of which break elongation is small in the direction in which break strength is large, when the break strength and break elongation of a separator are isotropic or non- isotropic. CONSTITUTION:When the break strength and break elongation of a separator are isotropic or non-isotropic an insulating porous film is used of which break elongation is small in the direction in which break strength is large. When a mechanical external force is applied to separators, they are almost simultaneously broken without being limited to a special direction such as the direction parallel or perpendicular to the winding direction. Therefore the area of breakage becomes large and the short-circuit current is not concentrated to a partial area, which represses abnormal temperature rise. It results in the improvement of safety.

Title: Coke oven
Inventor: NISHIWAKI JINICHI
IPC: C10B15/00
Filed: 1984-06-06
Abstract: PURPOSE:To make it possible to enhance heat conduction from a combustion chamber to a carbonization chamber and to quickly and efficiently produce coke, by enclosing the whole oven with a pressure-resistant, airtight enclosure and effecting carbonization under pressure. CONSTITUTION:The whole coke oven is enclosed with a pressure-resistant, airtight enclosure 7. The use of the apparatus enhances heat conduction from a combustion chamber 2 to a carbonization chamber 1 and that to material coal in the chamber 1, and effects quick and efficient production of coke because of high pressure in the whole oven. Since a high-pressure, high-temp. gas from combustion of pressurized fuel and pressurized air flows through the combustion chamber 2 and pressurized coal gas enters the chamber 1, difference in pressure on the both sides of the partition between the both chambers 1, 2 is small, so that it is possible to enhance heat conduction by decreasing the wall thickness. Said pressure difference is created by selecting the delivery pressures of compressors 8, 9, 10 or by handling a pressure control valve 12, so that the strength of the oven may be as before. The apparatus gives such an effect that it is possible to recover the heated, pressurized exhaust gas and coal gas as energy via gas turbines 13, 14.
